Description

Technical Field

[0001] This application relates to the field of battery production equipment, and more particularly to a flat ribbon cable and a formation and capacity testing equipment. Background Technology

[0002] Formation and capacity testing equipment is used in the core production process of battery formation and capacity testing. It plays a decisive role in the precise control of temperature, current, and voltage parameters, as well as the accurate sampling of battery data.

[0003] In traditional battery formation and capacity testing equipment, the low-current connecting wires and sampling lines often use ordinary single-strand or multi-strand wires. Due to the large number of lines, the layout of these wires is messy and space-consuming, significantly increasing the equipment assembly time and cost. For example, taking the sampling line connecting the battery module and the control unit as an example, traditional wires need to be connected and fixed one by one, resulting in long assembly time. Moreover, ordinary wires have poor shielding performance and are easily subject to interference in complex electromagnetic environments, which can easily lead to deviations in sampling data and seriously affect the accurate assessment of battery formation and capacity testing quality.

[0015] In one embodiment, the mating terminal is a snap-fit ​​terminal.

[0016] In one embodiment, the flat ribbon cable further includes a retainer for securing the ribbon cable.

Furthermore, the flat structure and orderly wiring characteristics of the flat cable significantly reduce wiring space, enabling tight arrangement within a limited space, greatly reducing space waste compared to traditional round conductors. On the other hand, the shielding layer covering the outer layer of the cable's insulating film provides excellent shielding, effectively blocking external electromagnetic interference and ensuring the high accuracy of sampling data using the flat cable.

[0032] In one embodiment of this application, a flat ribbon cable is provided for use in a formation and capacity testing device. (Reference) Figure 1 The flat ribbon cable includes a ribbon cable 110 and an insulating film 120. Figure 4 (As shown), shielding layer 130 and mating terminals 140. The ribbon cable 110 includes multiple parallel conductors arranged side-by-side, making the overall cable flat; the ribbon cable 110 integrates multiple conductors on the same plane, forming a unique ribbon cable structure. Specifically, the conductors can be arranged closely with zero spacing to reduce space occupation. At least one end of each conductor is connected to a device in the formation and capacity testing equipment. For example, one end of the conductor may be connected to a device in the formation and capacity testing equipment, and the other end may be connected to a device related to the operation of the formation and capacity testing equipment, such as the other end being connected to a battery module.

[0033] The mating terminal 140 is connected to one end of each wire in the ribbon cable 110. Specifically, the mating terminal 140 is located at the end of the ribbon cable 110 used to connect to the device in the formation and capacity testing equipment. Each wire in the ribbon cable 110 is connected to the device in the formation and capacity testing equipment through the mating terminal 140. The mating terminal 140 enables efficient wire-to-wire connection between the ribbon cable 110 and external connection terminals. Specifically, the mating terminal 140 may include multiple pins arranged side by side, with the number of pins being the same as the number of wires and each pin corresponding to a wire. The wires are connected to the device in the formation and capacity testing equipment through the pins of the mating terminal 140. For example, the pins of the mating terminal 140 may be made of elastic metal sheets. When the ribbon cable 110 is inserted into the mating terminal 140, the elastic metal sheets inside the mating terminal 140 can tightly fit the wire core of the ribbon cable 110, ensuring a reliable electrical connection.

[0034] The insulating film 120 is attached to the upper and lower surfaces of the ribbon cable 110 to cover and insulate it. Specifically, multiple conductors are arranged side-by-side to form a flat surface, with one side being the upper surface of the ribbon cable 110 and the other side being the lower surface. The upper and lower surfaces of the ribbon cable 110 include an upper surface and a lower surface. A shielding layer 130 covers the outer layer of the insulating film 120, facing away from the ribbon cable 110. That is, the ribbon cable 110 is first covered with an insulating film 120, and then a shielding layer 130 is placed over the insulating film 120. The shielding layer 130 effectively shields against external electromagnetic interference, ensuring high accuracy of sampling data, providing more reliable data support for battery formation and capacity testing, and significantly improving the quality of formation and capacity testing.

[0035] Specifically, the device used in the capacity testing equipment is, for example, a control unit. One end of the ribbon cable 110 is connected to the control unit via a plug-in terminal 140, and the other end is connected to the battery module, thereby using a flat ribbon cable to connect the control unit and the battery module to collect or transmit signals.

[0036] Specifically, a roller die technique can be used to process the ribbon cable 110 using a roller die to form a specific flat shape. The roller die is typically made of high-precision metal material, with a specific shape and size on its surface that matches the cross-sectional shape of the ribbon cable 110. During processing, the roller die gradually presses the ribbon cable 110 material into the required flat shape through rotation and extrusion, while simultaneously cutting and trimming the edges of the ribbon cable 110 to achieve the specified dimensions and precision requirements. Then, through roll forming, an insulating film 120 and a shielding layer 130 are sequentially applied to the ribbon cable 110, ensuring a tight bond between the ribbon cable 110, the insulating film 120, and the shielding layer 130.

[0037] The aforementioned flat ribbon cable employs a ribbon cable 110 with multiple conductors arranged side-by-side, each covered by an insulating film 120 and a shielding layer 130. One end of the ribbon cable 110 is connected to one end of the device in the batching and capacity testing equipment via a plug-in terminal 140. On one hand, the ribbon cable 110 integrates multiple conductors into a single unit, possessing the characteristics of a wire harness. During assembly, only overall installation is required, eliminating the need for individual wiring. Furthermore, the plug-in terminal 140 simplifies the connection to external terminals, greatly simplifying the equipment assembly process, shortening assembly time, improving production efficiency, and reducing production costs. The flat structure and orderly wiring characteristics of the flat ribbon cable significantly reduce wiring space, enabling a tight arrangement within a limited space, thus greatly reducing space waste compared to traditional round conductors. On the other hand, the shielding layer 130 covering the outer layer of the insulating film 120 of the ribbon cable 110 provides excellent shielding, effectively blocking external electromagnetic interference and ensuring the high accuracy of sampling data using the flat ribbon cable.

[0038] Applying the aforementioned flat cabling to formation and capacity testing equipment, specifically within the mechanical unit of the equipment, flat cabling replaces low-current (≤30A) connecting wires and sampling lines, achieving shielding of the sampling lines, space efficiency, and harness-like wiring. Taking the sampling line connecting the battery module and the control unit as an example, traditional wires need to be connected and fixed one by one. With flat cabling, one end of the flat cabling interface connects to the battery module sampling interface, and the other end connects to the control unit interface, saving 30% of equipment assembly time. Moreover, traditional wire arrangements have large gaps, while the flat cabling, through reasonable layout, can reduce the wiring space within the mechanical unit, strongly promoting the miniaturization and integration of formation and capacity testing equipment.

[0039] In one embodiment, the conductors of the ribbon cable 110 include a transmission line and a ground line, and the connector 140 includes a signal pin and a ground pin arranged side by side. Specifically, the ground line is connected to the ground terminal on the device of the forming capacity device through the ground pin of the connector 140; the transmission line is connected to the signal acquisition terminal of the device of the forming capacity device through the signal pin of the connector 140.

[0040] The signal pins and ground pins are made of metal. Specifically, the transmission line connects to the signal acquisition terminal of the device in the form-up testing equipment via the transmission pins, allowing the signal acquired at the other end to be transmitted and output to the signal acquisition terminal. The ground terminal on the device in the form-up testing equipment can be a grounding stud, and the grounding wire is connected to the grounding stud via the grounding pin to achieve grounding. A dedicated grounding pin is reserved in the mating terminal 140 to ground the grounding wire.

[0041] Furthermore, the external side of the plug terminal 140 can be provided with clear anti-misinsertion markings and a precise guide structure. During the equipment assembly process, the operator can quickly and accurately connect the flat cable to the external connection terminal according to the anti-misinsertion markings and the precise guide structure, which significantly improves the assembly efficiency.

[0042] In one embodiment, the grounding pin is silver-plated. Using silver-plated grounding pins increases the contact area, improves conductivity, ensures stable and reliable grounding, and further enhances the device's anti-interference capability.

[0043] In one embodiment, such as Figure 2 As shown, there are multiple ribbon cables 110. The connector 140 includes multiple rows of pins arranged in layers. Each row of pins is connected to one end of each wire in a ribbon cable 110, thus multiple ribbon cables 110 are arranged in layers, with each row of pins corresponding to a row of wires 110. By arranging multiple layers of ribbon cables 110, the number of wires in the harness can be increased, further reducing the space occupied. For example, a single layer of ribbon cable 110 may include 12 wires, i.e., 12 pins, arranged in 3 rows to achieve 36 pins.

[0044] In one embodiment, the lengths of the ribbon cables are different and increase / decrease according to the layers. Specifically, multiple wires within a single ribbon cable 110 are of the same length, while the wires in ribbon cables 110 located in different layers have different lengths, thus resulting in ribbon cables 110 of different lengths in different layers. By arranging ribbon cables 110 of different lengths in layers, it is suitable for connecting devices at different distances, which is convenient and practical. For example... Figure 2 In the middle, the topmost ribbon cable 110 is the shortest, and the bottommost ribbon cable 110 is the longest.

[0045] In one embodiment, the mating terminal 140 is a snap-fit ​​terminal. The snap-fit ​​design of the mating terminal 140 facilitates connection. For example... Figure 3 As shown, the plug terminal 140 is snapped into the socket provided on the metal panel of the control unit.

[0046] In one embodiment, such as Figure 1 and Figure 5 As shown, the flat ribbon cable also includes a retainer 150 for securing the ribbon cable 110. Specifically, the retainer 150 can be disposed on the shielding layer 130 for securing the ribbon cable covered with the insulating film 120 and the shielding layer 130 to other devices. By employing the retainer 150, the stability of the flat ribbon cable's placement position is increased.

[0047] For example, such as Figure 4 As shown, the fixture 150 can be a fixed cable clip, or more specifically, a fixed graphics card with a through-wall insertion structure. In use, the fixed graphics card is simply inserted into the control cabinet of the capacity-sharing device. Multiple fixtures 150 can be used, arranged according to the required fixing locations.

[0048] In one embodiment, reference Figure 1 and Figure 5 The aforementioned flat cable also includes an adapter connector 160, which passes through the through-holes in the shielding layer 130 and the insulating film 120 to connect to the conductors in the cable 110, thereby providing an electrical connection. By providing the adapter connector 160, it can be connected to other devices via external connection cables for signal conversion, offering greater ease of use. For example, the adapter connector 160 can be a terminal block, allowing external devices to connect to it via terminal block connectors.

[0049] For example Figure 5 As shown, there can be multiple adapter connectors 160, depending on actual needs. Furthermore, when the ribbon cable 110 is arranged in multiple layers, at least one wire in each layer of ribbon cable 110 can be connected to at least one adapter connector 160.

[0050] In one embodiment, the shielding layer 130 is made of copper foil. Using copper foil provides excellent shielding. Specifically, in practical applications, the copper foil shielding layer is reliably grounded to construct a complete shielding system, preventing external electromagnetic signals from interfering with the internal sampling lines.

[0051] In addition, this application also provides a chemical composition and capacity device, wherein the flat ribbon cable is used in the above embodiments.

[0052] The aforementioned flat cable can be used as a signal sampling line, temperature acquisition line, power line, fan line, etc., in a formation and capacity testing device. For example, as a signal sampling line, the flat cable has its connector 140 connected to the control unit's connector terminal, and the end opposite to the connector 140 connected to the positive and negative terminals of the battery module; as a temperature acquisition line, the flat cable has its connector 140 connected to the control unit's connector terminal, and the end opposite to the connector 140 connected to a resistor chip.

[0053] During the formation and capacity testing process, the flat cable rapidly transmits sampled data from the battery module to the control unit. Based on this precise sampled data, the control unit accurately regulates key parameters such as current and voltage during the process. For example, when the sampled data shows the battery voltage is close to the set cutoff voltage, the control unit can promptly adjust the charging current to ensure the safe and efficient conduct of the battery formation and capacity testing process. The flat cable-based formation and capacity testing equipment operates stably and efficiently. Building upon the achievements of shielded sampling lines, reduced space, harness-based wiring, and time-saving assembly, it further enhances the overall performance and production efficiency of the equipment through innovative connection structures and grounding methods.

[0054] The technical features described above can be combined arbitrarily. Although not all possible combinations of these technical features are described, any combination of these technical features should be considered to be covered by this specification, provided that such combination does not contain contradictions.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
